Project description

SSLyze

Run tests Downloads PyPI version Python version

SSLyze is a fast and powerful SSL/TLS scanning library.

It allows you to analyze the SSL/TLS configuration of a server by connecting to it, in order to detect various issues (bad certificate, weak cipher suites, Heartbleed, ROBOT, TLS 1.3 support, etc.).

SSLyze can either be used as command line tool or as a Python library.

Key features

  • Fully documented Python API, in order to run scans and process the results directly from Python.
  • Support for TLS 1.3 and early data (0-RTT) testing.
  • Scans are automatically dispatched among multiple workers, making them very fast.
  • Performance testing: session resumption and TLS tickets support.
  • Security testing: weak cipher suites, insecure renegotiation, ROBOT, Heartbleed and more.
  • Server certificate validation and revocation checking through OCSP stapling.
  • Support for StartTLS handshakes on SMTP, XMPP, LDAP, POP, IMAP, RDP, PostGres and FTP.
  • Scan results can be written to a JSON file for further processing.
  • And much more!
